1987 300D Turbo Fuel pump leaks

[theodorelucas]

Hi all,
I discovered fuel leaks on my injection pump at the delivery valves and ordered a 32 point female socket to replace the faulty o-rings. I have a handle on that one but there is another leak source. It is a 3 second drip from what appears to be a faulty gasket on a canister attached to the bottom right of the fuel pump assembly. It is just to the left of the engine mount strut that is bolted to the engine block with four 13 mm head bolts and the lower end of the strut rests on the motor mount. I can see the drip coming out of the bottom of the can with the help of a mirror. The can is attached to the aluminum billet housing and has a ring holding it with three thorax screws. Can anyone chime in as to where I can find any information to fix it? One outboard screw is accessible, the second inboard screw just barely, and the top third one not accessible. I don't know what the can does and hoping the gasket can be replaced without missing any adjustment up. It looks as it the pump has to be removed to get to it. I dred removing the pump and causing a new problem when putting the pump back right. Is removing the injection pump difficult? I have considerable mechanical experience with Mercedes and other cars, but not too familiar with injection pumps. Any leads appreciated,
Ted
